Abstract :The aim of this study was to compare ultrasonographic and laboratory findings in cases of lower urinary tract disease diagnosed in cats randomly brought to the clinic with urinary tract complaints. The study material consisted of 50 cats of different breeds, age and sex diagnosed with feline lower urinary tract disease. The diagnosis was based on anamnesis, clinical findings, urine and biochemical analyses and ultrasonographic findings. Serum biochemistry and urine analysis results and ultrasonographic examination data were evaluated comparatively. The results of the study emphasise that cases of lower urinary tract disease in cats are most frequently encountered in male individuals and that there are significant differences between breeds. In the study, the most common problems in 50 cats diagnosed with lower urinary tract disease were struvite crystalluria; 30% and idiopathic cystitis; 28%, respectively. The data obtained revealed a significant positive moderate correlation between resistive index and serum phosphorus values and a significant positive moderate correlation between resistive index and blood-urea nitrogen and creatinine. There was also a significant positive moderate correlation between resistive index and urine protein values. The mean serum blood-urea nitrogen, creatinine and phosphorus concentrations measured in cats with lower urinary tract disease were relatively high, although there were individual differences between the cases. However, it is noteworthy that the mean blood urea-nitrogen and creatinine values were within normal limits, although there were individual differences, especially in cases of partial obstruction. One-month follow-up showed that the blood urea-nitrogen, creatinine and phosphorus values measured at the first presentation to the clinic were higher in cats that died than in surviving animals. The data presented in this study also revealed the presence of a positive significant correlation between urinary protein and serum blood urea-nitrogen and phosphorus values. The ultrasonographic renal measurement data evaluated in this master thesis study were recorded within the average normal values, although there were individual differences between the subjects. The mean resistive index value measured was below the upper limit of normal of 0.7. The results emphasise the importance of comparative evaluation of all measurement data in the diagnosis, patient follow-up, prognosis and determination of the correct treatment method in cases of feline lower urinary tract disease.
